Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+3=x+15x+6−5
Step 1: Simplify both sides of the equation.
2x+3=x+15x+6−5
2x+3=x+15x+6+−5
2x+3=(x+15x)+(6+−5)(Combine Like Terms)
2x+3=16x+1
2x+3=16x+1
Step 2: Subtract 16x from both sides.
2x+3−16x=16x+1−16x
−14x+3=1
Step 3: Subtract 3 from both sides.
−14x+3−3=1−3
−14x=−2
Step 4: Divide both sides by -14.

ANSWER :
Surface area of larger cone : 24π units^2
Surface area of smaller cone : 6π units^2
The surface area of the smaller cone is 25% of that of the larger cone.
EXPLANATION :
From the given problem,
AB = 3 is the radius of the larger cone and the slanted height is BC = 5
DE = 1.5 is the radius of the smaller cone and the slanted height is EC = 2.5
Recall the surface area of the cone :
where r = radius and L = slanted height.
For the larger cone, r = 3 and L = 5
For the smaller cone, r = 1.5 and L = 2.5
Comparing the surface areas :
The area of the smaller cone compared to the larger cone is :
